BACKGROUND OF THE INVENTION

1. Field of Invention

Embodiments of the invention described herein pertain to electronicmotion sensing, communication of sensor-derived data, three-dimensionalgraphic display and gaming. More particularly, but not by way oflimitation, one or more embodiments of the invention enable a system andmethod for playing a game based on a coin toss that may utilize a systemand method for graphically displaying a coin toss using sensors todetect the physical movement of a coin, e.g., an instrumented coin orcoin observed by external sensors, communication of sensor-derived datato a remote graphical display system, and display of a virtual coin orgraphical coin that represents the movement and orientation of theactual coin.

2. Description of Related Art

During an athletic event, for example football or soccer, a coin toss isused to determine which team is given the choice of playing directionand/or possession of the ball, i.e., the initial advantage. Before thecoin toss, an official such as a referee will show both sides of a cointo the respective teams. The referee will toss the coin into the air,and one team guesses what side of the coin will face up when the coinlands on the ground. Only the referee and the team members in thevicinity of the coin toss see the movement and orientation of the coinas it is tossed. A coin toss may also be used for gambling, games andother entertainment.

A device which relates to a coin with any functionality other thancurrency is found in U.S. Pat. No. 5,619,066 filed Aug. 31, 1994 toCurry et al., which describes a coin shaped memory object (see Col. 2,ll. 14-31). The '066 device does not contain any instrumentation toprovide location, position, orientation or any other spatialmeasurement. In summary, there are no known coin devices that areinstrumented to provide their spatial information and communicate thatinformation for display.

Thus during a suspenseful part of the pre-game activities, thousands ofpeople viewing the game in the stadium and many thousands of peopleviewing on television (TV) cannot see the movement and orientation ofthe coin before, during, and after the toss. It would be beneficial toallow viewers to observe the coin toss without requiring that theviewers wait for the referee to announce the result. In addition, thereis no known system that allows viewers of the coin toss to play a gamethat allows the viewers to guess the result of the coin toss and win aprize based on the result of the toss. Hence, there is a need for asystem and method for playing a game based on a coin toss that mayutilize a system and method for graphically displaying a coin toss sothat the viewing audience may observe the coin toss as it occurs andobserve the result of the coin toss when the coin comes to a restingposition.

BRIEF SUMMARY OF THE INVENTION

One or more embodiments of the invention enable a system and method forplaying a game based on a coin toss that may utilize a system and methodfor graphically displaying a coin toss using sensors to detect thephysical movement of a coin, e.g., an instrumented coin or coin observedby external sensors, communication of sensor-derived data to a remotegraphical display system, and display of a virtual coin or graphicalcoin that represents the movement and orientation of the instrumentedcoin. Embodiments of the invention provide the following advantages.

Allows the anyone to see the movement and orientation of the coin andmore fully experience the coin toss:

-   -   Allows stadium or television viewers to experience the coin toss        as it occurs and instantly view the result of the toss when        integrated with a stadium large screen monitor such as a        JUMBOTRON®, with a television broadcast, or other devices.    -   Allows viewers to experience the coin toss in multimedia having        multiple aspects.

DETAILED DESCRIPTION OF THE INVENTION

A system and method for playing a game based on a coin toss that mayutilize a system and method for graphically displaying a coin toss usingsensors to detect the physical movement of a coin or an instrumentedcoin, data communication to a remote graphical display system, anddisplay of a virtual coin or graphical coin that represents the movementand orientation of the instrumented coin will now be described. In thefollowing exemplary description numerous specific details are set forthin order to provide a more thorough understanding of embodiments of theinvention. It will be apparent, however, to an artisan of ordinary skillthat the present invention may be practiced without incorporating allaspects of the specific details described herein. In other instances,specific features, quantities, or measurements well known to those ofordinary skill in the art have not been described in detail so as not toobscure the invention. Readers should note that although examples of theinvention are set forth herein, the claims, and the full scope of anyequivalents, are what define the metes and bounds of the invention.

Embodiments of the invention may include a sensor system, acommunication system and a display system wherein the display system maycouple with a game system and message gateway, for example a ShortMessage Service (SMS) gateway that interacts with cell phones. In one ormore embodiments, the sensor system and part of a wireless communicationsystem are embedded in a coin shaped housing. The display system andpart of the wireless communication system may include a remote station.The sensor system senses the coin's orientation, i.e. which coin face isup, and also senses the dynamic movements of the coin, if the coin ischanging its orientation or position. The game system may be utilized tocollect guesses from viewers via the message gateway, as sent in by theviewers using cell phones for example. The game system may then eitheralert all users who correctly guess the result of the coin toss thatthey have won a prize, or may utilize a random number or numbers toselect a subset of the viewers who have correctly guessed the result ofthe coin toss and alert the subset of viewers that they have won aprize.

Thus the sensor system senses which side is up and senses the dynamicsof motion and position when the coin is in the air during a coin toss.In one or more embodiments, sensor-derived data from the sensor systemis transferred to the communication system within the coin. In one ormore embodiments, the coin portion of the communication system uses datacommunication techniques to format sensor-derived data and wirelesslytransmit the data to the remote station.

The remote station's portion of the communication system uses datacommunication techniques and receives sensor-derived data from the coin,interprets the data, and transfers the data to the display system. Avirtual coin or graphical representation of the coin may be presented onthe display system. The graphical coin movement and orientation may bedisplayed by the display system in response to the sensor-derived datareceived from the sensor system. The graphical coin movement andorientation may mimic the actual coin being tossed or may be representedas any avatar or other graphical object that represents the coin, suchas brands, logos or for example, other information associated with asponsor. An example coin may depict a trademark or service mark or anyother saying or slogan as well, e.g., “tastes great” for “heads”, “lessfilling” for “tails”, or two rival beer company logos each representingone side of the coin where the winner of the toss gets a discount atconcession stands if the opening toss is won by a particular beercompany. For example, the coin may be represented by a celebrityflipping head over heels and landing “heads up” or “tails up”, i.e.,with their face showing or their “tail” showing. In one embodiment, this“heads” may be represented by one or more faces, such as the faces of acheerleading squad or beer representatives or models, while the “tails”portion may be represented by one or more reverse or “tail” views of thesame group or different group of individuals or other objects associatedwith the “heads” side. The numbers of objects representing the “heads”and “tails” may or may not be equal.

The graphical coin's starting orientation (heads or tails) and thegraphical coin's ending orientation may track the orientation of theactual coin being tossed within prescribed error limits. The startingand ending orientation (orientations that coin flipping audiencesgenerally care about) are usually important aspects of the coin toss asthey determine which team has the initial choice of direction, ball orother advantage. In one or more embodiments, the display systeminterfaces to a television broadcaster's network and/or to a stadiumlarge screen display. As such, using these embodiments detailed herein,viewers can see the virtual coin in any graphical depiction and observethe coin toss of the virtual coin.

Embodiments of the invention thus show viewers a graphical coin withheads up and tails up orientations to indicate the heads up and tails uppositions of the actual tossed coin. Embodiments show the viewersgraphical coin movement and orientation other than heads up and tails uporientations, for instance rotating in the air, in a way that isstimulating to the viewers and in a way that may reflect the actual coinmovement and orientation to any accuracy level desired. Hence,embodiments of the invention give viewers an enhanced, virtual view ofthe coin toss. Embodiments of the invention provide an opportunity forthe television broadcasters and stadiums to add a commercial sponsorduring the graphical, virtual coin toss.

Operation of an Embodiment—FIG. 3A

The logical sub-component block diagram is shown in FIG. 3A. Movementand orientation sensors 102 detect the movement and orientation of thecoin during the coin toss. There are many types of sensors that may beutilized in embodiments of the invention. In one embodiment, three-axisaccelerometers are utilized, however gyroscopes, light sensors, opticalsensors, magnetometers, and/or any other sensors may also be used insingular, multiple and in any combination. Sensor data is output fromthe accelerometers, and communicated to sensor processor 108 via theconnecting data path. The processor performs sensor processing of theraw sensor data to prepare the data for communication via RF Transmitter202. The sensor processing may include one or more of the following ornone.

-   -   Interpretation of the sensor data to translate the data into a        form more useful to other downstream system components.    -   Filtering of the sensor data to reduce the effects of random        perturbations in the data, fill in missing data and otherwise        make the data more representative of coin movement and        orientation.    -   Kinematics modeling of the coin, to allow sparse orientation        data to represent the full kinematics of the coin.    -   Interpretation to determine if the coin condition is in-flight,        launch, or captive, and optimize the data for those conditions.    -   Translating the data into a more compressed form to allow faster        communication, reduce communication latency and improve the        real-time response of the overall system. Compressing data        preserves the material content and reduces the amount of data to        be communicated. Decompressing occurs at the remote station to        reconstruct the material content.

Once the sensor data is processed by sensor processor 108, the data maybe formatted using data communication techniques in preparation for thedata to be sent to RF transmitter 202 for radio frequency transmissionto RF receiver 208. In this embodiment data communications formattingmay include CRC (cyclic redundancy check) data protection information,data framing and Biphase Mark bit encoding. In addition, data encryptionmay be used to secure the data. The data framing may include adding apreamble of zeros data. Forward error correction (FEC) can be used toadd data robustness beyond basic data protection. To mitigate RFI (RFinterference) from other RF devices in the vicinity, a frequency-hoppingmethodology may be used in any of the RF receivers and transmittersutilized in embodiments of the invention. Frequency hopping is known bythose skilled in the art. In this embodiment, the formatted data frameis sent to RF transmitter 202 via a data path that may for example beimplemented as a serial data path. The RF transmitter uses the formatteddata frame to modulate a radio frequency signal. The radio frequencysignal may be radiated via an antenna coupled with RT Transmitter 202.The antenna is not shown for brevity however it may be considered toreside internally on the RF transmitter 202. In one or more embodiments,the external housing of the coin may be utilized as an antenna. In orderto communicate the data, RF transmitter 202 may be configured andcontrolled by sensor processor 108 which may perform the necessaryconfiguration and control via a data path. Alternatively, theconfiguration and control may be communicated over a communications linkthat is separate from the data path used for the formatted data. RFtransmitter 202 as utilized may be an off-the-shelf module availablefrom commercial vendors, such as RF MONOLITHICS® or CHIPCON®. Dependingon the module, configuration and control may include, setting thefrequency, setting the data rate, setting the modulation technique, andcontrolling the transmitter output power.

The radiated radio frequency signal is transmitted over a distance andis received by RF receiver 208. In this embodiment, the signal isdemodulated and sent as demodulated data to receiver processor 308 via adata path that may for example be implemented as a serial data path. Aswith RF transmitter 202, RF receiver 208 may be an off-the-shelf moduleand may be configured and controlled by receiver processor 308 forexample. The demodulated data, e.g., the Biphase Mark serial data inthis embodiment is detected from noise by the receiver processor. Inthis embodiment, the sequence of zeros preamble data is detected fromnoise using a match filter digital technique. Once the preamble isdetected, the remainder of the preamble and subsequent data is detectedand decoded also using a match filter technique. The decoded data framemay be checked for errors using the data protection information.Erroneous data is thrown away and ignored. FEC may be used to correcterroneous data, rather than throwing the data away. If the date isencrypted, receiver processor 308 may be used to decrypt it. Onceprocessed by the receiver processor, the data frame represents thesensor-derived data frame from the coin. The sensor-derived data is sentto display computer 302 via a data path. In this embodiment, the displaycomputer uses the sensor-derived data from the receiver processor tocalculate the coin's movement and orientation and to show a graphicalcoin that may mimic the movement and orientation of the coin in the cointoss.

Any communication techniques may be utilized in communicatingsensor-derived data to the display computer, for example radiofrequency, light, infrared, optical or any other type of communicationchannel. For instance rather than transmitter and receiver, atransceiver could be used at each end and a send/retry technique couldbe used for data communication. Furthermore, the component utilized toprocess the data may be lie anywhere within the system, hence thelocation of data/communication processing as detailed herein may berelocated as one skilled in the art will recognize. For instance, FECmay be performed in sensor processor 108 or in RF Transmitter 202 or inthe receiver side of the system for receive side correction.

So that the graphical coin is responsive to the coin toss in real-time,system design for performance and overall latency is a consideration.Accordingly, the time to process the sensor-derived data, transmit thesensor-derived data, receive the sensor-derived data, calculate anddisplay the results may be implemented with any technique that allowsfor accuracy of the virtual coin flip to the desired level. In one ormore embodiments, the sensor-derived data and communication framing isconfigured to be small, and to employ a communication frame rate thatsupports the desired real-time responsiveness. For example, in oneembodiment a data frame rate of 60 frames per second is used at a baudrate of 38,300 although other frame and baud rates may be utilized toobtain the desired accuracy.

To conclude this section, for the operation of this embodiment anynumber of any types of sensors may be used, any processing of the sensorinformation may be performed. Any communication methods, communicationmediums, communication frequencies, or any combinations of these may beused.

Operational Calculations of an Embodiment—FIG. 6A, 6B

The discussion herein is in regards to calculations of parameters andvalues that may be used to manipulate a graphical coin or itsrepresentations.

The coin system side-view (FIG. 6A) shows the Z-axis of oneaccelerometer 101 and the Z-axis of the second accelerometer 103 in coinsensing system 400. The coin system top-view (FIG. 6B) shows the X1-axisof the coin on one accelerometer 101 and the X2-axis of the coin on thesecond accelerometer 103. The various axis measure acceleration in thedirection of the arrows in the figures. In this embodiment states areused to represent the different conditions of the coin and to processaccording to the specific condition. Those skilled in the art recognizethat in addition to a state-based scheme, there are many othertechniques that can be used. In this embodiment, each condition (state)is processed differently to represent the graphical coin on the display.The conditions are the “captive” condition, the “launch” condition, andthe “in-flight” condition. During the captive condition the coin isexperiencing the force of approximately one gravitational unit (1 G).The captive condition occurs when the coin is in someone's hand or lyingon the ground. The coin is in the launch condition when it isexperiencing significantly more than 1 G. In other words when it isthrown. The coin is in the in-flight condition when it is experiencingclose to zero Gs. In other words it is not touching anything and is infree flight. The condition (state) is determined by measuring Gs thatare being exerted on the coin. When the Gs exerted is close to 1 G, thenthe coin's condition is captive. When the Gs exerted is significantlymore than 1 G, then the coin's condition is launch. When the Gs exertedis close to zero Gs, then the coin's condition is in-flight.

During the captive condition, a tilt calculation uses the accelerometersand measures the gravitation force vector and determines the tilt angle(parameter) of the coin. The tilt calculation determines whether thecoin is heads-up, tails-up and any angle in between. The calculated tiltangle of the coin may be used to control the graphical coin and draw itat the same angle. The tilt calculation can be seen in the source codelisting in the calcAxisTilt( ) method of the Accelerometer class(Listing 1 immediately preceding the claims). During the captivecondition, the tilt calculation may provide an accurate indication ofthe coin's dynamic tilt angle as the coin is moving in the referee'shand. If a gyroscope is added, then the accelerometer based tilt anglecan be used to align the gyroscope in the captive condition. The dynamictilt control of the graphical coin results in tilt movements that arerealistic and accurate. The precision and realism of the graphical coinmay mimic the actual coin, may give the audience a realistic, virtualpresentation of the coin's movement both in the referee's hand and onthe ground. In one or more embodiments, the graphical representation maybe more realistic and accurate when it is most critical, before the coinis tossed and after the coin lands.

During the launch condition the force on the coin is in excess of 1 G.During launch an estimation of the coin's displacement (VDIS parameter)may be based on the acceleration during the throw. There is a VDIScalculation for the launch condition. The coin's rotational velocity(RVEL) may be fixed at zero during launch.

The VDIS calculation during launch uses the acceleration measured duringthe referee's throw of the coin. In the embodiment, the accelerationduring the throw is in excess of the normal 1 G resulting from gravity.The acceleration during the throw may be measured by the Z-axis of theaccelerometers (FIG. 6A, 101, 103). The VDIS calculation may useintegration of acceleration over time based on Newtonian Physics and canbe seen in the source code in the calcDisplacement( ) method for theLaunch class (Listing 2A immediately preceding the claims). Ofparticular interest in the listing is the deltaV calculation that uses(integrates) relative acceleration from the accelerometers and time. Thegraphical coin's displacement may be determined via this VDIScalculation. Thus the graphical coin's displacement may representativeof the actual coin's displacement during launch but may be scaled ortranslated in any manner during presentation to fit the screen utilizedin displaying the coin toss for example.

During the in-flight condition with the gravitational force on the coinclose to zero, in embodiments configured with only accelerometers assensors, the coin's tilt is difficult to exactly determine. However, thecoin's spatial position (displacement) and rotational velocity can beestimated. The in-flight condition may be very dynamic and fast moving,and the people watching the actual coin may not be able to tell itsexact movements. An estimation of the coin's displacement (VDISparameter) and rotational velocity (RVEL parameter) is sufficient forrealism. There may be two calculations for the in-flight condition, thecalculation for VDIS and the calculation for the coin's RVEL.

The VDIS calculation during in-flight may use a constant, i.e., theacceleration due to gravity. The VDIS calculation may use theintegration of acceleration of gravity over time, and may be based onNewtonian Physics for example as can be seen in the source code in thecalcDisplacement( ) method for the Launch class (Listing 2B immediatelypreceding the claims). Of particular interest in the listing is thedeltaV calculation that uses the gravitational constantG_METERS_PER_SEC2 of 9.81 meters/sec/sec and integrates it over time.The graphical coin's displacement may be determined via this VDIScalculation. Thus the graphical coin's displacement may berepresentative of the actual coin's displacement during flight.

The RVEL calculation for the in-flight condition may use the measuredacceleration of the coin's rotation to estimate rotational velocity. Thecombination of the coin's X1-axis and X2-axis accelerometers (FIG. 6B,101, 103) may be used to measure rotational acceleration. Thecombination of accelerometers is used in this embodiment, since theexact axis of rotation may be dynamically changing during the in-flightcondition. Any number and types of internal sensors may be used. TheRVEL calculation may also be based on Newtonian physics and can be seenfor example in the source code in the getRotationRate( ) method in theAccelerometer class (Listing 3 immediately preceding the claims). Theradius (FIG. 6B, R) from the center of rotation is related toacceleration and may be used in the calculation. The graphical coin'srotational velocity may be determined via the RVEL calculation. Thus thegraphical coin's rotational velocity may be representative of the actualcoin's rotational velocity.

In embodiments that employ a gyroscope coupled with the coin, the RVELcalculations may be more precise than the estimates for RVEL. In theseembodiments, the gyroscope may provide accurate rotational velocity. Thegyroscope may provide instantaneous coin angle information similar tothe roll, pitch and yaw angles provided by a gyroscope in an airplanefor example.

To conclude this section, for the operational calculations any formulaor technique may be used to determine any number of parameters or valuesbased on the sensing information from any number of any types ofsensors.

Operational Graphical Display of an Embodiment

The display of the graphical coin may be performed usingthree-dimensional (3D) graphics techniques. Only the high-levelprinciples used in this embodiment are described herein as one skilledin the art will recognize that any type of computer language or drawingtechnique may be utilized to display the virtual coin in any desiredmanner. In one embodiment, a scene is created, which contains a flatsurface that represents the ground. A light source is created to providelight on the scene, similar to the sun or other overhead lighting. Aproportionally accurate wire-frame model of the coin is created. Thecoin is rendered as solid shape and a bitmap image of the heads side ona real coin is “pasted” onto the heads side of the graphical coin. Abitmap image of tails on a real coin is “pasted” onto the other side ofthe graphical coin. The coin is positioned above the ground surface andbelow the overhead light source. A view port is created to set theviewing position in the scene. The view port can be considered thevirtual camera position as if a camera was being used. The result of thecreated scene is that realistic 3D coin is positioned over the groundsurface with a camera view. Many other scenes, many graphic techniques,any level of realism, and any representation of the coin may be used.

In addition to rendering the graphical coin with images of a real coin,many other images and imaging techniques can be used for rendering. Theimagines used can enhance advertising, such as having an automobile onthe heads side of the coin and a company logo on the tails side. Thecoin can also be rendered with moving images where each side of the coinis rendered with animated clips, video clips or even live video. Thegraphical portion of this invention can be tailored and evolved to meetthe changing needs of commercial usage and satisfy audience demand forstimulating new experiences. As previously discussed, human images suchas celebrity faces and reverse angle views of one or more persons may beutilized along with or in place of any other object or item that may beviewed and which may be utilized to represent the outcomes of a cointoss.

In this embodiment, 3D graphics transforms may be used and dynamic coinmovements may be added to the scene. In this embodiment, the coinmovements may be controlled using two transforms. One transform, thedisplacement transform, controls the coin's displacement (example:height above the ground surface). The other transform, the rotationtransform, controls the coin's rotation angle. In addition the view portmay be changed to give the best view of the coin toss, similar to acameraman panning and zooming to get the best view of a scene.Additionally the graphical coin may be scaled to grow or shrink the sizeof the coin. Any graphics technique and combinations of operations maybe used to manipulate the graphical coin.

During the coin's captive condition, using the displacement transformthe displacement may be held relatively constant above the groundsurface, at a height similar to being held in a person's hand. Duringthe captive condition, the tilt calculation discussed above is processedand passed to the rotation transform in the form of rotation angles. Asa result the coin may be suspended at a relatively fixed height over theground surface and may rotate practically in unison with the actualcoin. If the actual coin is flat with heads up, the graphical coin maybe flat with heads up. If the actual coin is heads up tilted 30 degrees,the graphical coin may be heads up tilted at close to 30 degrees. If theactual coin is flat with tails up, the graphical coin may be flat withtails up.

During the coin's in-flight condition, the displacement transform andthe rotation transform may both manipulated rapidly and dynamically tocontrol the graphical coin. The VDIS calculation discussed above may bepassed to the displacement transform to control the coin's displacementas a result of the toss. During the actual toss the graphical coin maymove upward similar to the height of the toss. Once maximum height isreached, the graphical coin may fall toward the ground and may stopapproximately when the actual coin hits the ground. Once on the groundthe graphical coin goes to the captive condition and may be displayed in3D as discussed in the previous paragraph. During the coin's in-flightcondition in parallel with the displacement, the RVEL calculation may beprocessed into a series of progressive rotation angles and may be passedto the rotation transform. The series of rotation angles change quickly,slowly or not at all depending on the value of RVEL. The result is thegraphical coin may rotate quickly, slowly, or not at all and may be anestimate of how the actual coin rotates. Since the displacementtransform and rotation transform are being manipulated nearly in unison,during the in-flight condition the graphical coin may appear to bedisplaced and rotating (flipping) at the same time. The visual effect isthat the in-flight behavior of the graphical coin may be perceived to besimilar to the in-flight behavior of actual coin.

In embodiments that employ a gyroscope coupled with the coin, therotation angles passed to the rotation transform may be more precisethan an estimate and may reflect the instantaneous angles of the tossedcoin. Thus with a gyroscope the graphical coin's in-flight rotation mayreflect the rotation of the tossed coin to any required accuracy and maybe synchronous with the rotation of the tossed coin.

Once the coin hits the ground and the condition is captive, thegraphical coin's rotation (tilt) angle may accurately reflect the actualcoin's angle to any required precision. For example, if the actual coinlands on a surface that is not entirely flat, i.e., the coin landssomewhat non-level, then the virtual coin may be displayed as completelylevel or at the actual angle of the coin, or from any viewpoint wherethe resulting heads or tails may be viewed. On the ground, theheads-up/tails-up state of the graphical coin may reflect theheads-up/tails-up state of the actual coin.

In addition to the aforementioned aspects of this invention, audio maybe incorporated into the effects of the coin toss. For instance, anaudio sound could represent the speed of rotation while in flight basedon the RVEL calculation. Another audio sound could represent thedisplacement of the toss based on the VDIS calculation. Yet anotheraudio sound could represent the coin landing on the ground. Anothersound such as a “ping” may be utilized to represent the referee'sinitial strike of the thumb against the coin at the initiation of thetoss.

Yet another addition to aforementioned aspects of this invention, pseudorandom number seeding and generation can be incorporated into the cointoss event. Data values such as the coin's height, rotation rate, timefrom toss to landing, or raw data from the sensors can be used to seedand generate a pseudo random number. Since many of the coin's datavalues are random in nature, the random number generated by a coin tosswill be less likely to be biased. For instance the height of any cointoss is unlikely to be same as any other coin toss, thus height is agood random seed. Many other data values or data sequences for the coinare also not likely to repeat. The practically unbiased random numberfrom a coin toss can be used to engage the coin toss viewer in games ofchance. For instance in the stadium the coin toss can be used to selecta certain seat in the stadium that will win a prize. Also the stadiumviewer's ticket can have a head's or tails printed on it that isselected by the viewer when the ticket is purchased. If the viewer makesthe same call as the coin toss, then a prize can be awardedappropriately.

To conclude this section, for the operation of the graphical display anytechnique may be used to make the graphical coin or its representationappear to move in response to any calculated parameters or values basedon the sensing information from any number of any types of sensors.

Coin Electronic Circuit of an Embodiment—FIG. 7

The block diagram FIG. 7 shows an embodiment of the invention shown withspecific implementations of the general components discussed elsewherewhich are not intended to be limiting values as other arrangements arewithin the spirit of the invention. Sensor processor 108 is implementedas a uProcessor (microprocessor). Accelerometers 101, 103 areimplemented as SPI (Serial Peripheral Interface standard) bus controlled3 axis accelerometers. RF transmitter 202, is implemented as a SPIcontrolled transmitter with antenna in the 900 MHz (megahertz) band.Other frequency bands can be used depending on the location oftransmission (the locality where the coin is being tossed). The powercontrol components include the magnetic reed switch 107, powercontroller 104, the rechargeable battery 105 and the power-inputcontacts 109.

The uProcessor controls and exchanges data with the Accelerometers andTransmitter via the SPI bus.

The operation of the power control components contributes to thepractical use of the invention. The power-input contacts provideelectrical contacts on the outside of the coin enclosure so thatexternal power supplied can charge the battery via the VinPlus andVinNeg lines. The Power Controller 104 takes battery input voltage andoutputs regulated Vdd voltage to the uProcessor. When controlled viaVpcControl, the Power Controller outputs regulated Vpc voltage to theAccelerometers and Transmitter. When near a magnet, the magnetic reedswitch signals the uProcessor via the MagSw line. Then the uProcessorwill turn off Vpc via the VpcControl line, which turns off thetransmitter and accelerometers. Connection with the power-input contactssupplies power so that the battery 105 is charged. Any other powerinput, power control, battery management, or battery charging techniquesmay be utilized.

Physical Construction of an Embodiment—FIG. 8

The enclosure 1004 of an embodiment of the invention provides mechanicaland environment protection for the coin's printed circuit board 1002.The enclosure provides space for the circumferential weight 1008 thatprovides balancing and to give the coin a feel and weight similar tothat of a real coin or any desired weight. The enclosure allows RFradiation from the internal antenna 1006 and provides mechanical supportof external power-input contacts 109.

Displaycomputer 302 may be implemented as a Personal Computer (PC) as shown orworkstation or integrated computing device in a broadcast trailer forexample which allows for the integration of other video with the displayof the virtual coin. RS 232 driver 304 allows uProcessor 308 tointerface via a standard RS232 communications port on PC 302. Powersupply 306 provides regulated power to the receiver electroniccomponents as per the Vdd input lines to driver 304, receiver 208 anduProcessor 308.

UProcessor 308 controls and exchanges data with 900 MHz Receiver 208 viathe SPI bus (shown as SPI line coupling receiver 208 with uProcessor308). UProcessor 308 exchanges data with PC 302 via the connection toRS232 Driver (connection shown as the RS232 Cable). The Power Supplyinputs external power and outputs regulated power that is distributedvia the Vdd lines. Any other serial or parallel communications protocolbesides RS232 may be utilized depending on the particular installationincluding more robust communications links that may be utilized in noisyenvironments for example.

The sensorprocessor is connected to the RF transmitter via a data path. The RFtransmitter is connected to the repeater receiver via a radio frequency(RF) communication link. The repeater receiver is connected to therepeater processor via a data path. The repeater processor is connectedto the repeater transmitter via a data path.

Operation of the Extended Range Embodiment—FIGS. 1B, 4B

The operation of the extended range embodiment may be similar to theoperation of other embodiments, except with regard to the communicationsbetween the RF transmitter 202, FIG. 4B and the RF receiver 208. In thisembodiment, the radiated radio frequency signal from the RF transmitteris transmitted over a distance and is received by the repeater receiver204. The repeater receiver is tuned to the same frequency as the RFtransmitter. The repeater receiver demodulates the RF signal. Therepeater processor 205 decodes the repeater receiver's demodulatedsignal, similar to the receiver processor decoding described in anembodiment. Using the decoded data, the repeater processor frames thedata similar to the sensor processor described in an embodiment. Theframed data is sent to the repeater transmitter 206 to modulate a RFoutput signal. The repeater transmitter may transmit on a differentfrequency than the RF transmitter 202. The radiated radio frequencysignal from the repeater transmitter is transmitted over a distance andis received by the RF Receiver 208. The RF Receiver 208 is tuned to thesame frequency as the Repeater Transmitter 206. Thus the repeaterreceives on one frequency and may transmit (repeat) on anotherfrequency.

The Repeater Receiver and the Repeater Transmitter are contained in therepeater station 500. The repeater station is able to be physicallylarger than the coin system 400. The larger size allows for a higherpower system, higher RF power output and a larger antenna. The repeatertransmitter can therefore have more effective radiated RF output powerand may have longer range than the coin system. The repeater station 500may be used on the playing field in close proximity to the coin toss.This close range allows the relatively weak RF transmitter in the coinsystem to be more easily received by the repeater station. The higherpower repeater transmitter may be better able to transmit at longerrange to the RF receiver that may be off the playing field.

The repeater station may also serve as a place to put the coin when thecoin is not being tossed. The repeater station may also serve as acharger for the coin systems internal battery. The coin system'srelatively low capacity battery may be charged from the higher-capacityrepeater station battery. The repeater station may have additionalcapabilities such as, but not limited to, a display and input device foruser interaction.

To conclude this section, for the extended range embodiment, anycommunication methods, communication mediums, communication frequencies,or any combinations of these may be used to extend range. Any processingof the data may be performed or none.

Description of the External Sensing Embodiment—FIGS. 1C, 2A, 2D

The components comprising the physical system of the external sensingembodiment of the present invention are illustrated in the block diagramof FIG. 1C. Coin 402 is sensed by the external sensing system 404 via asensing path. The sensing path can be a visible path for opticalsensing, a laser path for laser sensing or a path of another type forexample a magnetic path for magnetic sensing. The external sensingsystem connected to the remote station 600 via a communication link. Thecomponents comprising the logical system of an embodiment of thisinvention are illustrated in the block diagram of FIG. 2A. The sensorsystem 100 is connected to the communication system 200 by a data path.The communication system is connected to the display system 300 by adata path. FIG. 2D illustrates how the logical components aredistributed amongst the physical components in this embodiment of thisinvention. The coin system 2000 is contained in the physical coin 402.The sensor system and part of the communication system are contained inthe external sensing system 404. The display system and part of thecommunications system are contained in the remote station 600.

Operation of the External Sensing Embodiment—FIGS. 1C, 2D

The sensor system 100, FIG. 2D uses means such as an imaging systemsimilar to a video camera, laser scanning, or infrared sensors to sensethe external coin system 2000. The coin system may be an actual coin ormay be a coin-like object with or without passive features that enhancethe external sensor's recognition. Passive features such as reflectors,pattern coding, such as bar coding, or coloring may be used. Thecoin-like object may have active features, such as LEDs (light emittingdiodes), infrared emitters or other emitters that enhance recognition.The emitters may transmit in a steady state, may transmit codes orpatterns for recognition, or may transmit data to provide informationabout the coin object or its movement. The passive and/or activefeatures may be used singularly or in combination. Using enhancementfeatures or no enhancement features, the sensor system detects coinmovements externally and processes the coin's movements into orientationand spatial position (displacement) data. The orientation and positiondata are sent via the communication system 200 to the display system300. The display system processes the data and displays a graphical cointhat moves in accordance with the coin system.

Any image-processing algorithm or algorithms configured to recognize andtrack a coin from a sequence of images (image frames), for example takenfrom above, may be utilized. For the image processing discussion below,the images are taken from above, the coin's faces have different colors,and each face color contrasts with the normal background color. When thecoin is tossed, the coin's position in the image frame sequence may betracked using techniques such as “Kalman tracking of color objects” inU.S. Pat. No. 6,917,692 to Murching et al., filed on May 25, 1999.Another tracking technique is described in U.S. Pat. No. 7,187,783 toMoon et al., filed on Dec. 27, 2002. Using the frame position determinedvia tracking, the coin's outline may be detected from the background byimage processing algorithms such as Circle Hough Transform (CHT), it'sderivatives, Fast Circle Detection (FCD), or other techniques forreal-time circle or ellipse detection. One ellipse detection techniqueis described in U.S. Pat. No. 5,189,711 to Weiss et al., filed on Sep.9, 1991. The detected outline of the coin may change as the coin moves.If the outline is a circle then the coin may be determined to be in anear flat orientation. If the outline is ellipse shaped, then the ratioof the major and minor axis of the ellipse may determine the coin's tiltangle. If the outline is a line (degenerate ellipse) then the coin maybe determined to be in a vertical (edge up) orientation. A formulawritten in Java for calculating tilt angle given the axis ratio minordivided by major is shown in Listing 4. To resolve an ambiguity, theprior tilt angle is an input argument. The calculated tilt angle closestto the prior tilt angle can be used and the other ambiguous tilt anglescan be eliminated. Based on image frame rate, determining how fast theshape changes from a circle to a line may be used to determine thecoin's rotational velocity. A formula written in Java code forcalculating rotational velocity (RVEL) is shown in Listing 5. The inputargument numberOfFrames represents the number of frames that occursbetween the coin outline shape changing from a circle to a line. Whichside is up when the coin is oriented near flat may be determined byimage processing. For instance, detecting which of the two face colors(as described above) inside the coin's outline may be used to determinewhich coin face is up. Other techniques such as texture recognition mayalso be used to determine the coin's face up orientation. In a papertitled “Coin Recognition using Vector Quantization and HistogramModeling” authors Seth McNeill, Joel Schipper, Taja Sellers, Michael C.Nechyba describe such a technique. Determining the coin's displacement(VDIS) given the known height of the overhead camera may be accomplishedby calculating the range from the camera. U.S. Pat. No. 5,867,256 to VanRheeden, filed on Jul. 16, 1997 describes a method of range estimationusing image size measurements. Any of these algorithms, or any otheralgorithm for determining the orientation of a coin may be utilized inexternal sensing embodiments of the invention.

Thus using image processing techniques, coin movement and orientationcan be determined. Heads or tails up (face up) can be determined, thecoins tilt angle can be determined, displacement (VDIS) can bedetermined, and rotational velocity (RVEL) can be determined. Like thegyroscope implementation discussed in another embodiment, theinstantaneous coin angle information can also be determined. Using theseparameters, the graphical coin may be manipulated as described inanother embodiment and as in another embodiment the graphical coin maymimic the tossed coin. Similar to another embodiment the graphical coincan reflect the tossed coin as an estimate, exactly, or a combination ofthe two.

For the external sensing embodiment, the coin may have any activefeature, any passive feature or any combination or multiple of these forexternal sensing. The features may be external or internal to the coin.Any processing of the sensor information may be performed. Anycalculations, any formula or technique may be used to determine anynumber of parameters or values based on the sensing information from anynumber of any types of sensors.

The General Embodiment—FIG. 2A

In one or more embodiments of the invention sensing a coin's orientationand spatial position (displacement) during a coin toss occurs using anymethod or means, for example using sensor system 100. Likewise, datafrom the sensor system may be communicated using any method or means viathe communication system 200 to the display system 300. The displaysystem for example receives and using any method or means, interpretsthe data from the sensor system and displays a graphical coin that maymimic the actual coin. The graphical coin virtually represents theactual coin toss. The resulting virtual coin toss is shown to viewers.The virtual coin toss can be used for commercial purposes.

An embodiment of a method utilized in graphically displaying a coin tossis shown in FIG. 10. Processing includes activating an instrumented coinat 1901 wherein the activation of the coin enables the coin to transmitmovement data from the coin. The movement data may be detected bysensors at 1902 that may be coupled with the coin in some embodiments sothat movement may be directly measured other indirect measurementembodiments may be detected by sensors that are not directly coupledwith the coin for example. The movement data may be communicated via acommunication system at 1903. The movement may be displayed on acomputer display (for possible overlaying of video or other graphics toinclude with the virtual coin for example) at 1904. Any other method ofdisplaying a graphical coin that represents an actual coin toss is inkeeping with the spirit of the invention whether directly or indirectlysensed.

FIG. 11 illustrates the components used for a text-based game of chancein combination with other components of this invention. To simplify thediagram, the Display System 300 is shown without sensor system 100 andcommunication system 200 that may optionally couple with Display System300 in certain embodiments of the invention. The Display System 300 maybe coupled with the Game System 1100 via a data path. The Game System isconnected to the SMS (Short Message Service) Gateway 1200 via a datapath. The SMS Gateway is connected to a Cell Phone 1300 via a data path.The data path connecting the Cell Phone to the SMS Gateway, for examplemay be implemented with a cell phone service provider's radio frequencyinfrastructure.

Operation of Text-based Game with an Instrumented Coin and OtherComponents of this Invention

Yet another addition to aforementioned aspects of this invention, thepseudo random number as described in the display system section abovecan be used to select a winner from participating cell phone users whoare watching TV or other live video. This text-based game of chance,allows more than just the viewers in the stadium audience to be involveda game of chance. Any person with a text-capable cell phone can beinvolved. A specific description for a text-based game of chancefollows. Variations from this specific description are possible andthese variations are within the scope of this invention as thedescription of the game herein is exemplary only and is not intended tolimit the invention. For example, it is understood that a user on acomputer with access to a website may also play the game as long as thegame system is connected to the Internet for example.

Before the coin toss cell phone users who wish to participate send atext message to a destination shown to them on video, JUMBOTRON® or byother means. The text message can contain the viewer's input, i.e.,participant's guess of how the coin will land during the coin toss,i.e., the result of the coin toss after the coin has been tossed. Forexample, the participant can send a text message containing the letter“H” or word “heads” to guess that the coin will land heads up.Alternately the participant can be instructed to send a text message toone specific destination if they wish to guess “heads” or send toanother specific destination if they wish to guess “tails.” The textmessage for the participant's guess originates at a cell phone (FIG. 11,1300) and is communicated via the SMS Gateway (FIG. 11, 1200) to theGame System (FIG. 11, 1100). Numerous commercial providers can supplythe SMS Gateway or license its use. The Game System generates a uniquegame number (UGN) for the participant. In a record, the Game Systemstores the UGN, stores the guess (heads or tails), and stores theoriginating phone's identification (PID). The Game System sends the UGNin a UGN text message back to the participant. The Game System processestext messages and stores records for each participant that sends a textmessage.

After the coin has been tossed, the Display System (FIG. 11, 300) maysend the pseudo random number if less than the entire set of correctguesses is to be awarded prize(s) (as described previously in theGraphical Display section) and the coin's landing orientation (heads ortails) to the Game System. Based on the landing orientation, the GameSystem can prevent the records of participants who have made theincorrect guess from being selected as a winner. Using the pseudo randomnumber, the Game System can select the record of the winner or winnersfrom the participants who have made the correct heads or tails guess.Using the record of the winner, the Game System can send the UGN ofwinning participant(s) to the Display System. In one embodiment, theDisplay System can display the UGN and the UGN can be displayed to theTV or other live video. To claim the winning prize, the winningparticipant can compare the UGN on video to the UGN sent to him in theUGN text message. If the UGNs match, the participant can send a“Claiming” text message to a specific destination. There can be a limiton how much time can elapse before the participant can send the“Claiming” text message. The Claiming text message is sent via the SMSGateway to the Game System. Using the PID in the Claiming text message,the Game System compares the PID in the Claiming message to the PIDstored in the record of the winning participate. If the PIDs match, thenthe participant has successfully claimed the prize. In otherembodiments, the winner(s) of the game, i.e., those who correctlyguessed the coin to go to a particular location, for example to collecta prize such as a soft drink, food item, hat, or other prize.

In one or more embodiments of the invention, the viewer(s) who won thegame can be prompted to take a picture, for example of themselves whichcan for example be displayed (after management approval forappropriateness for example) on a JUMBOTRON® or on the television. Inaddition, if the viewer's cell phone contains a location device orlocation calculation capability, for example such as GPS, then thelocation can also be displayed, for example, “John Smith of San Diegohas guessed Heads and has won a prize”. Alternatively, the location canbe utilized to find the winning viewer in a stadium for example to pointthe cameras at the location of the winning viewer. Any other informationassociated with the winning viewer, such as a winning viewer textmessage, or sound, or any other data collectable from the viewer's cellphone (or computer for non-cell phone embodiments) may be utilized indisplaying information associated with the winning viewer(s).

In addition, other games of chance, such as a trivia game, dice roll, orany other type of game have a plurality of outcomes may be utilized toquery input from viewers that are then selected as winner(s), either asa group, a subset of the group or as an individual.

Operation of Text-based Game without an Instrumented Coin and with onlya Display System as Describe Herein

Operation is similar to the previous description up to where the coin istossed. Instead of the instrumented coin, a normal (non-instrumented)coin is thrown during the toss. After the coin has been tossed, anoperator manually interacts with the Display System and selects whatside of the coin landed up, heads or tails. Once the operator selectsthe landing orientation the Display System generates a pseudo randomnumber and sends the random number and the coin's landing orientation tothe Game System. The remainder of the operation is similar to thedescription using the instrumented coin.

In summary, the two text-based game of chance descriptions are differentwith regard to how the landing orientation of a coin toss is detectedand how the pseudo random number is generated. In one case, theinstrumented coin (or viewed coin) and other components of thisinvention supplies the landing orientation and generates and suppliesthe pseudo random number based on the dynamic data of the instrumentedcoin. In the other case the landing orientation is detected by a personand manually inputted into the system, and the random number isgenerated by the system without being based on instrumented coin dynamicdata.

The use of the unique game identifier that is input as viewer inputallows a time window to start wherein viewer input after a predefinedtime window associated with the unique game identifier are disabled. Forexample, viewers that are not watching a commercial where the game isannounced in a portion of the screen, cannot win since they input theirguess after the time window closes. This ensures that only viewers thatare watching the commercial win for example, which can be utilized toincrease commercial viewing.

While the invention herein disclosed has been described by means ofspecific embodiments and applications thereof, numerous modificationsand variations could be made thereto by those skilled in the art withoutdeparting from the scope of the invention set forth in the claims.
